Q

25
Information Provision
When the government intervenes to provide information to correct market failure
26
Luxury Goods
YED>1; an increase in incomes causes an even bigger increase in demand
27
Market Failure
When the free market fails to allocate resources to the best interest of society, so there is an inefficient allocation of scarce resources
28
Market Forces
Forces in free markets which act to reduce prices when there is excess supply and increase them when there is excess demand
29
Maximum Price
A ceiling price which a firm cannot charge above
30
Minimum Price
A floor price which a firm cannot charge below
31
Mixed Economy
Both the free market mechanism and the government allocate resources
32
Negative Externalities of Production
Where the social costs of producing a good are greater than the private costs of producing the good
33
Non-Excludable
A characteristic of public goods; someone cannot be prevented from using the good
34
Non-Renewable Resources
Resources which cannot be readily replenished or replaced at a level equal to consumption; the stock level decreases over time as they are consumed
35
Non-Rivalry
A characteristic of public goods; one person’s use of the good does not prevent someone else from using it
36
Normal Goods
YED>0; demand increases as income increases
37
Normative Statement
Subjective statements based on value judgements and opinions; cannot be proven or disproven
38
Opportunity Cost
The value of the next best alternative forgone
39
Perfectly Price Elastic Good
PED/PES=Infinity; quantity demanded/supplied falls to 0 when price changes
40
Perfectly Price Inelastic Good
PED/PES=0; quantity demanded/supplied does not change when price changes
41
Positive Externalities of Consumption
Where the social benefits of consuming a good are larger than the private benefits of consuming that good
42
Positive Statement
Objective statements which can be tested with factual evidence to be proven or disproven
43
Possibility Production Frontier (PPF)
Depicts the maximum productive potential of an economy, using a combination of two goods or services, when resources are fully and efficiently employed
44
Price Elasticity of Demand (PED)
The responsiveness of demand to a change in price %change in QD divided by %change in P
45
Price Elasticity of Supply (PES)
The responsive of supply to a change in price %change in QD divided by %change in P
46
Price Mechanism
The system of resource allocation based on the free market movement of prices, determined by the demand and supply curves
47
Private Cost/Benefit
The cost/benefit to the individual participating in the economic activity
48
Private Goods
Goods that are rivalry and excludable
49
Producer Surplus
The difference between the price the producer is willing to charge and the price they actually charge
50
Public Goods
Goods that are non-excludable and non-rivalry
51
Rationality
Decision-making that leads to economic agents maximising their utility
52
Regulation
Laws to address market failure and promote competition between firms
53
Relatively Price Elastic Good
When PED/PES>1; demand/supply is relatively responsive to a change in price so a small change in price leads to a large change in quantity demanded/supplied
54
Relatively Price Inelastic Good
When PED/PES<1; demand/supply is relatively unresponsive to a change in price so a large change in price leads to a large change in quantity demanded/supplied
55
Renewable Resources
Resources which can be replenished, so the stock of resources can be maintained over a period of time
56
Scarcity
The shortage of resources in relation to the quantity of human wants
57
Social Cost/Benefit
The cost/benefit to society as a whole due to the economic activity
58
Social Optimum Position
Where social costs equals social benefits; the amount which should be produced/consumed in order to maximise social welfare
59
Specialisation
The production of a limited range of goods by a company/country/individual so they aren’t self-sufficient and have to trade with others
60
Specific Tax
A tax imposed on a good where the value of the tax is dependent on the quantity that is bought
61
State Provision of Goods
Through taxation, the government provides public goods or merit goods which are underprovided in the free market
62
Subsidy
Government payments to a producer to lower their costs of production and encourage them to produce more
63
Substitutes
Positive XED; if good B becomes more expensive, demand for good A rises
64
Symmetric Information
Where buyers and sellers both have access to the same information
65
Trade Pollution Permits
Licenses which allow businesses to pollute up to a certain amount. The government controls the number of licenses and so can control the amount of pollution. Businesses are allowed to sell and buy the permits which means there may be incentive to reduce the amount they pollute
66
Unitary Price Elastic Good
When PED/PES=1; a change in price leads to a change in output by the same proportion
67
Utility
The satisfaction derived from consuming a good
68

70

73
Competitive Market

Herding
Where people take decisions based on the actions of others, rather than on a rational evaluation of the situation they face
77
Internalising an Externality
An attempt to deal with an externality by bringing an external cost or benefit into the price system
78

79
Marginal Cost
The cost of producing an additional unit of output
80

The additional benefit that society gains from consuming an extra unit of a good

Marginal Social Cost
The cost to society of producing an extra unit of a good
